A supramolecular polymer was constructed from a light-driven overcrowded alkene switch modified with two alkylated gallic acid amide pendants (MSP-1). Upon UV irradiation, stable MSP-1 isomerized into unstable MSP-2, which induced the effective collapse of well-defined cross-linked supramolecular polymers, and the reassembly can be realized by aging at low temperature.
